Antioxidant, antimicrobial and anti-inflammatory activities of ling-heather honey powder obtained by different methods with several carriers

Honey powder is being increasingly used in food, cosmetic and pharmaceutical industry, because it avoids inconveniences of raw honey, such as high viscosity, stickiness formation sugar crystals. It paramount importance to know if honey powders keep the features honeys. This first study, which total phenolics, flavonoids, biological properties ling-heather (Calluna vulgaris (L.) Hull) obtained by different drying methods (spray drying, vacuum freeze drying), using carriers (Arabic gum, whey protein isolate maltodextrin) were assessed. Results showed that all procedures retained phenolics powders. powders' antioxidant activities against free radicals (ABTS•+, ROO•, •OH O2•-) higher than those honeys, while powders’ anti-inflammatory antimicrobial several microorganisms (Staphylococcus aureus, Listeria monocytogenes Escherichia coli) lower. Concentration type carrier for dehydration key factors quality However, procedure did not strongly influence parameters studied.
